TONGUE-TRUCK FOR DISK HARROWS.

Application filed June 24, 1907.

To all whom it may concern:

Be it known that I, Mosns 1V. KOUNS, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented certain new and useful Improvements in longuelrucks forDisk Harrows, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The present invention relates to tongue trucks for disk harrows andimplements of a similar character.

The object of the invention is to provide a truck of this characterwhich can be used either with or without a tongue, and which, when usedwithout a tongue, will be readily steered by the draft eveners; whichwill be provided with suitable means for detachably securing the tonguethereto; and which can be strongly braced. without interfering with theturning thereof.

With these objects in view my invention consists in certain novelfeatures of construction and in certain parts and combinationshereinafter to be described, and then more particularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation of a diskharrow equipped with my tongue truck, showing the same provided with thetongue; Fig. 2 is a similar View, showing the truck without the tongue;Fig. 3 is a front elevation of the truck the double-tree andstrap beingremoved; and Fig. 4 is a vertical sectional view, taken on the line a;a: of Fig. 3.

In these drawings, I have illustrated the preferred form of myinvention, and, as therein shown, the same consists of a main frame 1having its lower end bifurcated to form the arms 2, each of which isapertured near its lower end to receive an axle 3 which is securedtherein and upon the outer ends of which are journaled the ground wheels4. The frame 1 may be connected to the disk harrow or other implement inany suitable In the form here shown, I have provided a harrow 5 with astub tongue 6, preferably consisting of a flanged metal beam extendingforwardly from the harrow, and have connected the forward end of thisstub tongue to the frame 1. I prefer to form this connection by means ofa coil ling member or plate 7 which has one end irmly secured to thestub tongue in any suitable manner, as

by means of the bolts 8 and 9, and has its for-" Specification ofLetters Patent.

ward end projecting beyond the end of said stub tongue and provided withan aperture adapted to receive the upper end of a bolt 10 which extendsthrough a suitable portion of the main frame 1, thereby pivotally.connecting said frame to said-tongue. I prefer to provide the main framewith a bearing aperture 11 extending vertically through the same andadapted to receive the bolt 10 which extends through the same and isprovided at its lower end with a nut 12 for re taining the same inposition. A suitable brace 13 preferably extends between the lowerportion of the main frame of the truck and the stub tongue 6. I haveherein shown the preferred form of this brace which consists of a metalbar secured between the flanges of the stub tongue and having its lowerforward end. apertured and adapted to engage the lower end of the bolt10, thus forming a strong brace for the truck and removing the strainfrom the coupling member 7. This brace being arranged centrally of thetruck, does not interfere with the turning of the same.

The main frame 1 is provided with suitable means for detachably securingthereto a tongue. This means preferably consists of a forwardlyextending socket which, as here shown, consists of a forwardly extendingplate 14 having downwardly extending side members or flanges 15, betweenwhich the end of the tongue 16 is secured, preferably by means of a bolt17 extending through the tongue and through the side members 15 of thesocket near the lower 'edges thereof, thus leaving considerable spacebetween the tongue and the upper plate 14 of the socket and permittingthe tongue to be moved vertically about its pivotal center through aconsiderable space and affording a very easy means for removing andattaching the tongue. The main frame of the truck is preferably providedwith suitable draft even ers which may be secured thereto in anysuitable manner, but I prefer to secure the draft eveners or doubletrees18 at a point in front of the main frame, and this I accomplish bysecuring the same near the outer end of a forwardly extendingprojection, which projection, in the present instance, is shown as theupper plate 14 of the tongue socket, the draft eveners being pivotednear the forward end thereof by means .of a bolt 19 extending throughthe plate 14 and the eveners I 18. A suitable hammer strap 20engages'the upper end of the bolt 19 at one end, as shown, and the upperend of the bolt 10 at the opposite end.

Thus, it will be seen that I have provided a tongue truck of thecharacter described which is readily adapted to be used either .with orwithout a tongue and is provided with a tongue socket within which thetongue may be secured and removed with a slight effort; that I haveprovided means for attaching the eveners to the truck in such a mannerthat the truck is readily steered with the eveners alone, this beingaccomplished by securing the eveners to aforwardly extending projectioncarried by the main frame of the truck and further, that I have provideda suitable brace extending between the lower end of the main frame ofthe truck and a suitable part of the harrow frame, such as the stubtongue, which brace relieves the strain u on the coupling memberconnecting the stu tongue to the main frame of the truck, and this braceis arranged centrally of the truck and in such relation thereto that thetruck can be readily turned about a vertical axis to a sufficient extentfor steering the harrow without the wheels coming into contact with thebrace.

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is z- 1. In a tongue truck of the characterdescribed, the combination, with an implement to be guided, and a stubtongue therefor, of

lower end of said bolt and its other end connected to said stub tongue,ground wheels for said frame, a tongue adapted to be secured thereto,and a draft hitch connected to said truck at a point in front of saidframe.

2. In a tongue truck, a frame comprising a vertical member having itslower portion bifurcated, a forwardly extending socket secured near theupper end thereof and having its lower portion cut away, a tonguepivotally mounted in said socket, a draft hitch secured to the upperside of said socket near the forward end thereof, and ground wheelssupporting said frame.

3. In a tongue truck, an integral frame comprising a vertical standardhaving a longitudinal aperture, a bifurcated portion, the arms of saidbifurcated portion being provided with bearings, an axle mounted in saidbearings, ground wheels mounted on said axle, a projection extendingforwardly from the upper portion of said vertical standard, downwardlyextending side members having their upper edges secured to saidprojection and their rear edges secured to said vertical standard, atongue pivoted near the lower edges of said side members, and means forsecuring a draft hitch to said projection.

In testimony whereof, I aflix my signature in presence of two witnesses.
